Genes affected

RSPRY1 (HGNC:29420): (ring finger and SPRY domain containing 1) This gene encodes a glycoprotein that contains a RING-type zinc finger domain and an SPRY domain of unknown function. Alternative splicing of this gene results in multiple transcript variants. [provided by RefSeq, Feb 2015]

ACMG classification

Verdict is Likely_benign. Variant got -1 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• BP4: Computational evidence support a benign effect (MetaRNN=0.10301107).
• BS1: Variant frequency is greater than expected in population afr. gnomad4 allele frequency = 0.0000394 (6/152180) while in subpopulation AFR AF= 0.000145 (6/41446). AF 95% confidence interval is 0.0000628. There are 0 homozygotes in gnomad4. There are 4 alleles in male gnomad4 subpopulation. Median coverage is 32. This position pass quality control queck. Existence of Clinvar submissions makes me limit the strength of this signal to Supporting

Algorithms developed to predict the effect of missense changes on protein structure and function (SIFT, PolyPhen-2, Align-GVGD) all suggest that this variant is likely to be tolerated. In summary, the available evidence is currently insufficient to determine the role of this variant in disease. Therefore, it has been classified as a Variant of Uncertain Significance. ClinVar contains an entry for this variant (Variation ID: 1348788). This variant has not been reported in the literature in individuals affected with RSPRY1-related conditions. This variant is present in population databases (rs377663780, gnomAD 0.01%). This sequence change replaces glutamine, which is neutral and polar, with arginine, which is basic and polar, at codon 59 of the RSPRY1 protein (p.Gln59Arg). -
